particularly set forth A upper ends are pivotally connected to the plate8. Thus, it will be seen that since the plates 7 and 8 are parallel andthe bars 9 and 10 are parallel, the plates 7 and 8 will always bepositioned parallel to each other irrespective of the direction in whichthe plate 8 is shifted with respect to the plate 7. The arms or bars 9and lOat each side of the machine are preferably connected intermediatetheir ends by a linkll.

At the rear end of the machine is rotatably mounted a rockshaft 16 whichextends between and beyond the side frame members 1. On this rockshaftat the outer sides of the frame are secured arms 17 which are pivotallyconnected at their free ends to links 18, which links are pivotallyconnected at their forward ends to the links 11 intermediate the ends ofthe latter. It will be noted that the links 18 are connected to thelinks 11 so as to increase the length of the links 18. On therockshaft16, at the end thereof nearest the operator, is mounted anoperating handle 19 for rotating the rockshaft and thereby shifting theplate 8 toward and away from the plate7.

At the forward end and preferably at the upper side of the plate 8 isremovably mounted an arbor on which is mounted a roll of sheet material27 which may be in the form of rubberized fabric. The arbor 27 isnonrotatable,but is readily removable so that a portion of the sheetmaterial may be unwound for easily and quickly renewing the worn outportion of the sheet material. The free end of this sheetmaterialextends backwardly in loop form, as indicated by 2711., and thenforwardly over thetop of the plate 7, as indicated by 27?), and thenaround the forward rounded end of the plate 7 and backwardlybetween theside frame members 1, as indicated by 270. The rear end of the latterportion 270 is secured to a bar or arbor 28extending between andsupportedby and at the lower ends of arms 29. These arms 29 extenddownwardly from the rear edge of the plate 7 between the side framemembers 1, but adjacent the inner side thereof, as shown best in Fig. 5.Also supported by the arms 29 and above the bar or arbor 28is aremovable rod 30 over or around which is looped a flexible member 31,which may be of the same materials as the flexible sheet 27.

This flexible member 31 which serves 'pri-. manly as a connectingbelt,extends around a roller 32, mounted on the rockshaft 16, and thentoward the rear end tion 27 a of the sheet member 27. The forward end oredge of the flexible member or belt 31 is secured to the looped; portion27a, as shown best in Fig. 6. The securing means in this instanceconsists of arod 33 loosely positioned at the rear end of the loopedportion 27a, and a channel member 34 of more than semi-circular extent.The forward end of the looped porof the flexiblemember or belt 31 isextended around the looped rear end of the portion 27 a and the channelmember 34 is extended around the forward end of the member 31, thusreadily detachably securing the sheet members 27 and 31 together. Thus,there is formed an endless loop which extends over the upper side of theplate 7 and a portion of which is drawn back and forth'over the plate bythe arms 29. V

The operation of themachine is briefly as follows:

A piece of dough or other similar product, as indicated by'A' in Fig. 3,is placed upon theportion 27b of the flexible sheet in front of theplate 7. The handle 19 is then rotated in a clockwise direction forcingthe plate 8 in the direction of the arrow and at the same time forcingthe same angularly or diagonally toward the plate 7. The portion 27 b isdrawn backwardly from the forward end of the plate 7 causing the pieceof dough or other product to be brought under the plate 8 and theportion 27a'of the flexible sheet, compressing the piece This piece ofdough or other product will be pressed into circular form of uniformthickness. When the plate 8 is forced forwardly, all of'the flexiblemembers become taut, as indicated by dotted lines in Fig. 3, thusproviding smooth forming surfaces at the adjacent sides of theformingplates. The handle is then shifted in a counter clockwisedirection, causing the plates to separate, the portion 27?) of theflexible member 27 to be drawn forwardly over the plate 7 and conveyingthe formed productover the forward edge of the plate 7 into the hand ofthe operator or on to any suitable receptacle or conveyor, not shown. r

' The thickness of the formed product may vary depending upon the limitof space between the plates 7 and 8. This space is adjusted by a stop 35at one side of the machine. This stop is adapted to be engaged by one ofthe arms 17 as the same is shifted forwardly.

It will be here noted that when the operating lever 19 is shifted tosubstantially its extreme forward position, the pivotal connectionbetween the lever 19 and the link 18 is substantially in-alignment withthe pivotal axis of the arms 17and the pivotal connection between thelinks 18 and the links 11. Thus, considerable force may be exerted bythe lever 19 in forcing the plates 7 and 8;together. i

Though I have shown and described a particular construction, combinationand arrangement of'hparts and portions, I do not wish to be limited tothis particular construction, combination and arrangement, but desire toinclude in the scope of'my invention the construction, combination andarrangement substantially as set forth in the appended claims. a

of dough or other product.
